- This invention relates ,to bearings andto' a method of manufacturingthe same and more particularly; to flanged bearingsand of producing typeof bearings r I Y The invention relates particularlyto an improvedmethod of manufacturing 'bearg ingbacks for flanged bearings andcontemplates pre-forming a tubular-body, pre form ing a flange member ora'pair offlange-mem bers and subsequently uniting said member;

or members to one or both; ends respectively of thetubular body. Withsuch alm'ethod' it is possible to manufacture steel backbear: ings orbacks for bearings ofa materialwhieh can not be conveniently oast.- Byreason of the present invention it isfilsQipossibleto pre-form theflanges any desiredor preferred manner of any desired material similarto or different from the tubular body por- "The several objects,advantages and novel v details ofconstruction of this invention togetherwith the several stepsof our irnproved method will be made more apparentas time 1 description proceeds especially-,Wheujcon- *sidered inconnection withthe accompanying drawings wherein V J I v Figure 1 is aplan View of the material from which the tubular body member is preformed.

In making: abearing flanged at both ends 10. such asillustrated inFigure 1 is formed in any desired'man'ner to form a tubular bodymember11 such as illustratedin end elevationliniFigure 2. The sheet ofmaterial 10inay1be formed intothe'tubularfibody 11in any id'esirledmanner such as by pressing, stamping, rolling. orv any other formingoperation Likewise the invention material lOis to be made of steel,nevertheless the tubular-. body members may be made in i any desired orpreferred material; as will be I immediately obvious. i 1

a In Figuresj 3and4 a pre-formed flange member is l illustrated, thisflange. member being formed of any desired materialsimilar to ordifi'erent fromthe material of which the tubular body made." The flangemembers maybe pre -formed in any desired manner, :as for instance, byrolling the same from a stripof material; or casting the same ;,or forinstance they may be made of stampingstma chined or unmachined as foundto bed'esirable orexpedient; Inthe embodiment of the in- I.:vention.hereinillustrated each flange member is substantially Lrshapedin cross section to v providealaterally extending base or leg '14 ofadia1neter substantially coincident with outabuttingrelationwith theends of the tubular body member 11 whereupon the flange mem- .be'rs,maybe rigidly permanently secured to .theitubula'r body 11 as'for instanceby weld-1 ing, the lines of weld being indicated in Figure 6 by thereference character 15'. Ohviously when the outer surface of the bearingback is later machined these ridges or uneven surfaces at the lines ofweld are removed. This invention,- however, contemplates uniting theflange members with the body member in any other desired manner. Forinstance, the flanges may be secured to the body member by being pressedor seamed thereon or by brazing or sweating the same thereto.Furthermore the engaging surfaces may be tinned and the flanges unitedwith the body by the bond provided by the tin. Also it is possible tocast the flanges on to theendsof the tubular body membentheinvention'contemplating any means whereb the flanges are permanentlrigidly united with the body.

In Figure 7 a bearing flanged at both ends and babbitted as at 16 isshown partially in longitudinal sectidn and partially in elevation. Inthis View the babbitt is shown as extending around the ends of thebearing and on to the outer faces of the flanges as indicated M 17. Whenthe bearing backs are babbitted in this manner the outer faces of theflanges are countersunk or recessed as indicated at 18 to receive acoating ofbabbitt on the faces thereof. 1 V

' In Figure 8 a half bearing 19 is illustrated which may be produced bythe herein describedinethodbypracticing the further step of severin thewhole bearing in half longitudinally t ereo'f alonga line'cdincidentwith i the seam 12 With the present invention, when employed in themanufactnre of half bearin 'sthe bearings may be made oversize in t emanner described and claimed in United States Letters PatentsNumbered1,554,493 dated september22,1925 and 1,402,849 dated Jannary 10,Accordingly such bearings may be made interchangeable as well as ofstandard construction. p

In Fignre 9 a tribular bearing 20 having a single flange is illustrated.Such bearings may be man H v provisions of this invention but. undersuch conditions only one flange member 13 will be attached to thetubular body member 11.

Reservation is made to make such changes in the details of constructionand in the several steps of the method as well as the sequence of suchsteps as may come within the purview of the accompanying claims.

What we claim as our invention is 1. In the method of mannfacturingbacks for flanged half bearings, those steps which consist in shaping anut sheet by forming operations to produce a tubular body, preforming bysuitable operations a flange memher having a laterally extending base ofa diameter substantially coincident with that of said tubular body,connecting said parts by means which results ina fusion orintegrafactu'red in accordance with the tion of the material thereof andlongitudinally severing the structure into halves.

2. In the method of manufacturing hacks for flanged bearings, thosesteps which consist in shaping a flat sheet by forming operations toproduce a longitudinally split tubular body, pre-forming by suitableoperations an inte ral flange member having a laterally exten ing baseof a diameter substantially coincident with that of said tubular" bodyconnecting the edge of the base of said flange member to the end of saidtubular body by means acting to cause a fusil union between the parts,and halving the structure by severing the same longitudinally on a planecoincident with said split.

In the method of forming backs for flanged bearings, those steps whichconsist in shaping a flat sheet of material into a cylindrical bodyhaving a longiudinal split,

pie-forming a flange member to provide a ring-like member substantiallyL-shaped in cross section with the base of the L of substantially thesame diameter as said cylindric'al body, bringing the base of saidflange member into engagement with the end of said body, permanentlyintegrating said engag ing portions, and forming the structure intohalf-bearings by severing the same along aline coincident with saidsplit.

4; In the method of forming flanged half bearings, those steps whichconsist in shaping a flat sheet of materialinto a cylindrical'botly,'-pre-'for'ming a flange memberto provide a ring-like membersubstantially L- shaped in cross section with the base of the L ofsubstantially the same diameter as said cylindrical body, uniting saidbody and flange member by butt-welding the edge of theba'se of saidflange member to the end of Said body babbitting the inner surface orthe resulting structure, and severing the structure in halflongitudinally thereof. g 5. The method of forming a bearing whichconsists in shaping a flat sheet of material into a cylindrical body,--')re-forming a flange member with arecess in one face, securing saidflange member to the end of the said tubular member, and babbit-ting theinner periphcry of the said tubular member and the inner periphery andrecessed face of the said flange member;

In testimony whereof we aifix our signature's.
